From my collection, an envelope featuring the Disney-designed Seabee insignia for the 60th Naval (Canal) Construction Battalion in 1943. The design was one of several made by Disney artists for various Seabee units.
An interesting component of this insignia is that the unit's motto, "Can Do," was incorporated into the design. The word "do" is spilling out of the "can" the bee has kicked. Also, when viewed under a magnifying glass, printed on the rolled up paper the bee holds in his hand are the words, "Plans, Tokyo Highway."
